RIVETING- MACHINE.

SPECIFICATION forming part of Letters Patent No. 699,707, dated May 13, 1902.

Application filed October 26, 1900. Serial No. 34,501. (No model.)

To a, whom it nuty concern:

Be it known that I, HENRY O. POMEROY, a citizen of the United States, residing at Ohicago, in the county of Cook, State of Illinois, have invented certain new and useful Improvements in Adjustable Riveting-Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to adjustable riveting-machines, and particularly to such a machine in which the anvil or die may be adjusted in its relation to the plunger for use with different-lengths of rivets.

The invention has for its object to provide a device for quickly adjusting an anvil or die and holding the same in an adjusted position, so that the machine is adapted to operate with different lengths of rivets.

A further object of the invention is to pro- 'vide an improved structure of casting or housing adapted to receive and contain the operating parts in the most economical manner and in the smallest possible space, so as to provide a tool which can be operated in the. hands of the user or attached to a foundation.

Other objects and advantages of the in vention will hereinafter appear in the following description, and the novel features thereof will be particularly pointed out in the appended claims.

In the drawings, Figure 1 represents a side elevation of the device with the anvil shown adjusted to an advanced position and the plunger lowered in dotted lines. Fig. 2 is a perspective of the casting adapted to receive the parts of this invention. Fig. 3 is a side elevation with parts in section showing the plungerand die in position when a rivet has been set, and Fig. a is a detail perspective of the die-adjusting lever and cam.

Like letters of reference indicate like parts throughout the several figures of the drawings.

In the drawings the letter A represents a casting which is of particular construction for use in connection with the present invention. A, having a curved rear outline, as shown in Fig. 2, whereby it is adapted to be grasped in the hand if the tool beused as a hand device, and the forward end of this base is provided This casting is provided with a base with suitable securing-lugs A projecting laterally therefrom. At the upper portion of the casting a neck A is formed, and extendin g upwardly therefrom are the pivoting-ears A adapted to receive the die-adjusting device 13. Under these lugs and the extended neck a plunger-case A is formed and at its upper portion an apertured face-block A is provided upon which the material may rest. In the curve of the neck and at one side thereof a lateral rib or projection A is provided, which acts as a stop to limit the upward movement of the operating-lever O for the plunger. This casting may be apertured in any desired manner and at suitable positions to reduce the weight thereof and economize in the manufacture while retaining sui'ficient rigidity and strength for the purposes of the invention. The brace-rib A, which connects the base A with the rear of the neck A may be suitably curved, so that the lower portion lies in a different vertical plane from the upper portion, and thus permit the free operation of the plunger-lever in the lower portion of the casting. At the outer end of the neck A and at the lower portion of the cars A a die or anvil D is mounted, which may be of any desired construction, but in the present instance is shown as provided with a laterally-extending head D, between the under face of which and the upper face of the casting an elevatingspring D is located, so as to normally raise the die and hold the same in contact with the adjusting-faces 13 upon the adjusting device B.

It will be obvious that this device may be of various constructions; but in the present illustration of the invention it is shown as provided with a pivoted lug B journaled at the upper portion of the lugs or cars A and provided with an operating-lever B When 'journaled in this position, the several faces operating with this anvil or die is a plunger E; provided with a transverse head E and a retracting-spring E bearing against one face of said head and lying within a suitable re cess A", formed in the casing A at the base of the casting. This plunger reciprocates through the apertured face A, 'upon which the work is adapted to rest. The plunger is actuated by any suitable form of leverfor instance, a lever O, pivoted by means of a bolt passing through the lever and casing. This bolt is also adapted to hold in position the cover-plate F, which fits the face of the casing A and protects and conceals the operating mechanism for the plunger. The in nor end of the lever O is formed with an angle-arm C adapted to operate against the under face of the plunger-head E and elevate sential that the anvil or die be located a proper distance above the face A, through which the plunger operates for each thickness of material used, and consequently thelength of rivet employed. This is essential for the reason that if the material be notheld against upward movement when the rivet rises with the plunger the rivet will probably be turned over or partially headed before it can force its way through the material. WVhen the parts are in the position shown in Fig. 1, the rivet is dropped into the aperture and rests upon the face of the plunger E. The material to be riveted is then placed upon the face A" and the anvil or die adjusted by means of the lever B so as to be in intimate proximity to the upper face of the material to be riveted. The outer end of the lever O is then depressed, which raises the plunger and the rivet, forcing the latter through the material and into contact with the headingface of the die or anvil. rial is to be riveted, the die would be adjust- If very thick mateed as shown by full lines in Fig. 1, While if the material is of a thin character the die would be adjusted closer to the face A as I shown by dotted lines, and for various thicknesses of material the intermediate faces 13 can be employed. In operating. the invention the same may be grasped in one hand of the operatonwith the fingers beneath the and other parts either for the purpose of ornamentation, economy of construction, or the attachment of auxiliary devices without departing from the spirit of ,the invention as defined by the appended claims.

Having described my invention, what I claim is 1.
